REGENERATOR OF ABSORPTION REFRIGERATION CYCLE

PROBLEM TO BE SOLVED: To contrive the reduce the size and simplify the structure of an absorption refrigeration cycle machine on the whole and reduce the number of components or the weight by forming the end of a steam outlet of a vapor liquid separation section as a steam inlet header of a low temperature regenerator. SOLUTION: A low concentrated absorption liquid is introduced into a low temperature regenerator 3 from an absorption liquid inlet 37 and diffused in the vessel with a diffusible inner pipe 38 where a refrigerant is heated with a heating pipe 35 and absorbed, is partially evaporated and introduced into a condenser laid out close to the low temperature regenerator 3 by way of an eliminator 39. The medium- concentrated absorption liquid produced by evaporating the refrigerant flows out from an absorption liquid outlet 41 and sent to a high temperature regenerator 1. The liquid heat-exchanges with a high temperature gas burnt in a combustion chamber 22 and reaches a vapor liquid separation section 13 where it is turned into a high- concentrated state and sent out from an absorption outlet 20. The refrigerant vapor separated in the vapor liquid separation section 13 by way of an eliminator 18 flow into an inlet header 31 of the low temperature regenerator 3 and is liquefied while passing through the heating pipe 35 and flows out from a refrigerant condensed liquid outlet 4.
